Also explictly mark which instructions are specializable in stats. It is not the job of the summary script to guess which instructions are specializable.

Per instruction stats now look like:

LOAD_METHOD_NO_DICT: 488505073 0.7% 84.8%
    Misses: 5702208 1.2%
STORE_ATTR_INSTANCE_VALUE: 485786899 0.7% 85.5%
    Misses: 6904720 1.4%
BINARY_OP_SUBTRACT_INT: 460413189 0.7% 86.2%
    Misses: 2710155 0.6%
...
